Following a rough spell for the pop superstar (he and girlfriend Selena Gomez recently split, then there was the alleged pot-smoking photo scandal, followed by the paparazzo killed while trying to shoot picture's of the singer's car), Justin posted a photo of himself mooning the camera to his Instagram account on Saturday.

The picture was quickly deleted, but not before it hit 86,000 likes - you can see the photo HERE.

The Biebs' manager, Scooter Braun, took to Twitter to joke about the cheeky photo (using perhaps the best hashtag of the week), writing, "as a prankster u have to respect another good prank. only makes sense. #crackdealer"

The "Beauty and the Beat" singer kept his reply short and sweet, Tweeting, "Haha."

And it seems Justin is getting quite comfortable in his adult skin.

In addition to sharing his backside-baring pic, the singer stripped off his shirt during his Nashville concert on Friday night, showing off his red boxer briefs and leaving little to the imagination as the waistband of his pants was sagging far below his waist. See the photo HERE.
